Minimizing grid use

Novel battery system could reduce buildings' electric bills

I don't know what to make of this, but in some places (like all of Australia from about Sydney up), it's easy to imagine that domestic large scale batteries to store excess electricity generated by solar panels during the day could mean a house uses very little electricity off the grid.  If, say, an extra $10,000 on a new house build could give a very large saving on electricity use both during the day and night, would it make more sense to do that rather than having solar panels that feed back into the grid?  It would at least avoid the problems to the grid that feed in solar panels can cause.
